DeleteMessage

Deletes the specified message from the specified queue. You specify the message by
using the message's receipt handle and not the MessageId you receive when you send the message.
Even if the message is locked by another reader due to the visibility timeout setting,
it is still deleted from the queue. If you leave a message in the queue for longer
than the queue's configured retention period,
Amazon SQS automatically deletes the message.

Note

The receipt handle is associated with a specific instance of receiving the message.
If you receive a message more than once, the receipt handle you get each time you
receive the message is different.
If you don't provide the most recently received receipt handle for the message when
you use the DeleteMessage action, the request succeeds, but the message might not be deleted.

For standard queues, it is possible to receive a message even after you delete it.
This might happen on rare occasions if one of the servers storing a copy of the message
is unavailable when you send the
request to delete the message. The copy remains on the server and might be returned
to you on a subsequent receive request. You should ensure that your application is
idempotent, so that receiving a message more than once
does not cause issues.
